ELECTRIC RECEIVING DEVICE.

Specification of Letters Patent.

Patented April 2, 1907,

Application filed September 8,1906. Serial No. 333,846.

To all witom it may concern:

Be it known that I, IsIDoR KITsEE, a citizen of the U mted States, residing at Philadelphia, in the county of Philadelphia andl .wellknown siphon-recorder, an instrument now mostly employed in cable transmission, it being understood that the device may be used for electric transmission of intelligence other than telegraphic, and instead of the siphonrecorder other recording or relaying devices may be operated thereb In the drawings I have oniy illustrated that part of a siphon-recorder which is essential to show the working of my device when recording the received impulses.

- Referring to the drawings, Figure 1 is a perspective view of part of a siphon-recorder and a side view, part in section, of my receiving device. Fig. 2 is a plan view of the diaphragm employed in said device.

In the drawings, 20 is my receiving device as an entirety, comprising a permanent mag-- net 1, here shown in the shape of a horseshoe and having at one of its terminals the N pole and at the other of its terminals the S pole. To these poles are secured the electromagnets 2 and 3, respectively, the coils of which are joined at 19. The terminal 17 of these coils is connected to one part of the line of transmission 22 and the terminal 16 of said coils is connected to the other part of said line. In proximity to the core of the electromagnet 2 is the vibrating diaphragm 7, provided with the polarized armature 5, and in proximity LO the core of electromagnet 3 is the vibrating diaphragm 6, provided with the armature 4-. These diaphragms or disks are secured by the To the center of the diaphragm 7 is secured the fiber 9, and to the center of the diaphragm 6 is secured the fiber 10. These fibers are connected with their other terminal to the siphon cradle 11,- secured to the bracket 12. To the cradle is secured the siphon 3, one end of which is immersed in the ink 15 and the other end of which is in proximity to the paper 14. This paper is supposedto be moving at a predetermined speed.

I have not shown here the vibrating mechanism usually attached to siphon-recorders, as the mechanism and office of same is well understood.

The operation of this device is as follows: Normally both diaphragms will remain stationary at their zero position; but when an impulse is impressed upon.- the line of a polarity so as to make the corev end near the armature 4 say north then the center of the diaphragm 6 will be drawn inward; but as at the same time the same impulse will produce a south pole of the core near the armature 5 this armature will be repelled, and the center of the diaphragm 7 will be thrown outward, and if the impulse impressed is of an opposite polarity the operation is reversed. Through these movements of the diaphragms the cradle, and therefore the siphon, will be rocked, and this rocking motion will produce on the paper a record similar to the record produced. by the siphon-recorder of to-day. It is obvious that with such arrangement the received impulses may not only be recorded, but also relayed, if the siphon or the metal substituted therefor is made to operate a local circuit.

Having now described. my invention, what I claim as new, and desire to secure by Letters Patent, is'

1. A receiving device for electric transmission of intelligence comprising a permanent magnet, an electromagnet for each pole of said magnet, a vibrating diaphragm for each ofs'aid electromagnets, and means to connect to each of said diaphragms a localized device adapted to be actuated through the movements of said diaphragms.

2. Means to receive impulses impressed upon a line of transmission. and translate the same, said means embracing two vibrating diaphragms, an electromagnet for each .of said dia hragms, means to induce magnetic lines of 'orce in the'core of each of said electromagnets, a siphon-recorder, and means to induce movements in said siphon-recorder through the movements of both of said diaphragms.

3. In electric transmission of intelligence,

a receiving device comprising two electromagnets', a vibrating dia hragm for each of said electromagnets, a polarized armature for each of said diaphragms, means to induce magnetic lines of force locally in the cores ofsaid electromagnets, a translating device, and means to operate said translating device through the movements of both of said diaphragms.

4. In combination, a receiving device and a localized translating device, both operativelyrelated to each other, the receiving device inserted in the line of transmission and comprising two telephonic receivers, the vibrating diaphragms of both receivers provided With polarized means and adapted l i i g i l I ISIDOR KITSEE.
